Cooling performance data notes
• All capacities include indoor fan heat. kW values are for the system (outdoor + indoor).
Multipliers for determining the performance with other
indoor sections
Note: For dry bulb temperatures different than those listed (between 73°F to 87°F), sensible
capacity increases by 1060 Btu/h per 1000 CFM per degree above the listed temperature and
decreases by 1060 Btu/h per 1000 CFM per degree below the listed temperature.
